THE PUPAE OF WEST AFRICAN MOSQUITOS. 



Genus Mimomyia, Theo. 



89 



Edwards in his " Revised Keys to the Known Larvae of African Culicinae " has 

 given a table by means of which the pupae of M. splendens, M. plumosa, M. mimomyia- 

 formis, and M . hispida can be distinguished. In the following notes we give certain 

 additional points of importance with regard to two of these species. 



Mimomyia mimomyiaformis, Newst (fig. 14). 



The pupa as a whole is dark, and the paddles and the middle parts of the abdominal 

 segments are covered by minute spines. The paddles are pyriform, the inner distal 

 angle, however, is characteristically squared ; they are infuscated with a white

comma-shaped marking on their outer sides ; there is a fringe of large sparsely 

 scattered points ; the midrib is well developed, and there are single short terminal 

 setae. The tufts at the posterior angles of the 8th segment are very small and consist 

 of only 2 or 3 short hairs. On the 7th segment there are only a few minute setae near 

 the posterior angle, and on the posterior margin a little internal to these two rather 

 larger bifid setae. The latter setae are better developed on' the anterior segments, 

 and are further subdivided. The dendritic setae on the 1st segment are poorly 

 developed and but little branched. The trumpets are long and pale at the tips. 



Mimomyia splendens, Theo. (fig. 15). 



The paddles are narrow, ending in a small knob-like projection, and slightly 

 darkened at the tips. There is a well developed buttress both on the inner and outer 

 margins of the paddles, but the midrib is poorly developed distally. The fringe on 

 the paddles is long. The terminal setae are small, and there is a small seta close to

the midrib a little distance from the end. The tuft at the posterior angle of the 8th 

 segment is poorly developed and consists of only one or two short hairs ; the pos- 

 terior angle itself is almost tooth-shaped. At the posterior angle of the 7th segment
